Synology DX1215II storage drive enclosure HDD/SSD enclosure Black

The operating frequency of the alternating current supplied to an AC adapter, expressed in hertz (Hz). It indicates the mains frequency range that the charger can handle and ensures proper operation with the connected device.

The range of alternating current voltage that an AC adapter can accept, expressed in volts (V). It specifies the minimum and maximum supply voltages compatible with the device, ensuring safe operation across different regions and power standards.

A list of official certifications or compliance marks that the product has received from regulatory bodies, safety organizations, or industry standards groups. Each entry represents a distinct certification such as CE, FCC, RoHS, UL, or WEEE, and may include additional details like version numbers or specific test reports.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

The linear measurement across the widest part of a fan, expressed in units such as millimeters (mm), centimeters (cm) or inches (in). It represents the overall width of the fan and is useful for determining fit, compatibility with cases, and airflow characteristics.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

Indicates whether the product can have storage units inserted or removed while it is powered on and running without needing to shut down or reboot the system.

The largest amount of digital storage that a product can hold or provide, expressed as a numeric value with an appropriate unit such as GB, MB, TB, or a descriptive label indicating the type of media (e.g., SSD, HDD). This attribute helps users understand how much data can be stored on the device and compare storage options across products.

The total count of individual cooling fans that are part of the product or its components. This value indicates how many separate fan units are installed, such as in a graphics card, CPU cooler, case, or other hardware assemblies.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The main electrical supply that powers the device, such as mains electricity (AC), battery, USB power, PoE, or a combination of these options.

The physical width of a storage drive measured in inches or millimetres, typically expressed as the diagonal size of the drive’s enclosure (e.g., 2.5" or 3.5"). This measurement indicates the form factor that determines compatibility with computer bays, external enclosures, and mounting brackets.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

List of physical or logical interfaces that allow an internal storage drive to communicate with the system, such as SATA, M.2 PCIe, U.2, SAS, NVMe, or other standard connections.

A list of environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.

Indicates whether the product has a USB interface for data transfer or power delivery. A value of "Yes" means at least one USB port is present; "No" indicates no USB ports are available.

The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.
